[QUOTE="Mulz, post: 6000220, member: 486357"] [h2]Homework Statement [/h2] Two lenses with the focal length of 50 mm are placed tightly. An object is placed 130 mm away from the lenses. Where is the image generated by the lenses? [h2]Homework Equations[/h2] [tex] \frac{1}{a}+\frac{1}{b}=\frac{1}{f} [/tex] [tex] L = f_{ocular} + f_{objective}[/tex] [h2]The Attempt at a Solution[/h2] [/B] Frankly, I tried starting out by simply using the first equation. I got b to around 81 mm to the right. I don't know if it's correct. The question never specifies which type of lens (convex or concave). Doesn't specify which kind of optical setup (meaning I don't know if to use the second equation). I thought about dividing the problem with respect to each lens but I don't know the kind of lenses used so I have no clue. [/QUOTE]
